The idea isn’t exactly mine; I’ve watched a couple of YT videos based on the same principle. Here I link my own ‘composition’ 
and performance, the ‘one chord’ being Cm7 with the lead line fully improvised. The rhythm you hear is me tapping lightly on my guitar strings somewhere down the neck.
As it’s just one chord, nothing complicated, I thought it would be great to hear the proposals of others in any instrumental arrangement.
